2023-04-28 updates:

-- fixed Normal/Hard choice at the start, moving some variables to global
-- filled in some missing storylines when you had a good session
-- fixed bug where chapter 7+ (book 1) or chapter 6+ (book 2) reported erroneous bug. There is text instead to nudge solving.
-- when the game exits, you now get a <press key to exit> nudge, so the screen text doesn't disappear right away.
-- enhanced end-of-game text
-- AX and CX now give extended ABOUT and CREDITS, instead of ABOUT twice
-- added convert12.py utility that lets you see the conversion in the walkthrough between book 1 sequences and book 2 sequences

2023-04-21 updates:

-- put in choice at the start to enter Normal or Hard mode, so the user knows they're there.
-- clarified use of P to list progress and sequences. PP and PPP now show more detailed and potentially spoiler-y stuff.
-- colorama loader tweaks. We can now proceed without colored text, with asterisks provided in place of colored text.
-- more game text has colored text formatting now.
